With the development of the times, people are no longer unfamiliar with "urbanization", and the prosperity and splendor of modern cities have become commonplace. However, with the further development of urbanization in China, "urban diseases" have become increasingly prominent. Some people jokingly say that going from one city in China to another, sometimes you really wonder if you are still circling in the original city. Currently, shared bicycles have greatly facilitated people's lives, but some of our cities have extremely poor infrastructure and lack bicycle lanes. In addition, problems such as urban environmental pollution and noise pollution are also very prominent. It can be said that the "uniform" architectural styles between our cities, the various irrationalities in the urban planning process, and various problems that arise during urban operation... all of this has brought very serious consequences to our urban life. It is against this background that building smart cities has become an inevitable choice for China's new urbanization development.

Market Size of Smart Cities

　　It is reported that since the Ministry of Housing and Urban-Rural Development first proposed the concept of smart cities in 2010, the development of smart cities in China has been carried out vigorously. The construction of smart cities is a very large-scale system project, with a large number of upstream and downstream relationships in the industrial chain. According to the deployment of relevant national ministries and commissions to promote the construction of smart cities, it is expected that by the end of 2017, the number of cities in China that have launched and are under construction of smart cities will exceed 500.

　　According to the prediction of the Foresight Industry Research Institute, the market size of China's smart city market in 2017 will exceed 6 trillion yuan, with a compound annual growth rate of about 32.64% in the next five years, and the market size will reach 18.7 trillion yuan in 2021.

　　Smart cities have a huge scale and immeasurable application potential. From the perspective of industry, it is mainly based on the collection of big data such as wisdom and digital data, which will have a profound impact on other industries. For example, the development of smart cities will drive the development of IT, the Internet of Things, and advertising media.

Opportunities and Challenges for LED Display Enterprises

　　Currently, the annual investment in smart cities in China is growing rapidly and has entered a period of comprehensive explosion. For LED display enterprises, this is undoubtedly an opportunity that cannot be missed. Therefore, how to get a share of the pie in the wave of smart city construction has naturally become a must-answer question for the LED display industry.

　　The construction of smart cities is comprehensive, and those closely related to us include construction, transportation, education, and sports. These fields are also closely related to our LED display enterprises. From the perspective of application, LED displays can be seen everywhere in today's cities, in the fields of outdoor advertising, video surveillance in security fields, transportation systems, urban landmark buildings, etc. It can be said that our LED displays play a huge role in various fields of urban life. Therefore, some people believe that the biggest function of LED displays is nothing more than display, no matter how the city develops, as long as the LED display does its "primary job" well, the smart development of the city has little to do with it.

　　Indeed, in terms of display technology, our LED display companies have been working diligently. After so many years of development, the display effect of LED displays has basically met the basic needs of various application fields. With the maturity of future small-pitch technology, the display effect will become better and better, and the application fields of LED displays will continue to expand.

　　However, if LED display companies are only satisfied with the pursuit of display effects and do not keep up with the times and the trend of the times, and continuously improve and enhance the various functions of LED displays, they will be in a "lagging" position in the development of smart cities.

　　This is not alarmist. Take outdoor LED displays as an example. LED displays, with their high brightness and strong adaptability to various harsh environments, have the characteristics of anti-corrosion, waterproof, and moisture-proof, and have almost dominated the outdoor display market. However, in recent years, the number of LED displays that have been removed due to safety issues or light pollution issues is not small.

　　The core content of the development of smart cities is people-centered, in order to allow us humans to have a better livable life and environment. If our LED display companies cannot effectively solve some of the existing problems, cannot do everything "people-oriented", and cannot better allow LED displays to coexist "harmoniously" with people, they will not be able to have a bright future.

LED Display Enterprises Contribute to the Development of Smart Cities

　　It is gratifying that since the state first proposed the concept of smart cities in 2010 and implemented it, it has been seven years. During this period, many LED display companies have actively responded to the country's call and contributed their own strength to the development of smart cities.

　　As mentioned earlier, a smart city is a very large-scale system project, and the construction of smart cities involves all aspects of the industry. In the fields of roads, construction, transportation, sports, and education that are closely related to LED displays, some LED display companies have already taken the lead in joining the ranks of smart city construction. For example, in the field of transportation, the intelligent transportation system is one of the most important links in the construction of smart cities.

　　Intelligent Transportation System (ITS) effectively integrates advanced science and technology (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations research, artificial intelligence, etc.) into transportation, service control, and vehicle manufacturing, strengthening the connection between vehicles, roads, and users, thereby forming a comprehensive transportation system that ensures safety, improves efficiency, improves the environment, and saves energy. For LED displays, LED variable message signs on highways, intelligent bus electronic station signs, etc., LED displays can play a major role. The most familiar one is the LED lamppost screen. Lamppost screens have the characteristics of synchronous reception and synchronous playback. Lamppost screens not only have unique advantages in road guidance, road condition broadcasting, information dissemination, and advertising promotion, but also play a certain role in alleviating driver fatigue on highways.

　　Another important area of smart city construction is construction. Imagine that when you drive home, without any buttons, the garage door opens automatically, when passing through dark roads, the streetlights will automatically increase the brightness, smart displays will issue weather forecasts or various warning information, and smart home appliances will also provide convenience for life... For LED displays, to achieve these, it is not enough to limit themselves to the display function, but to integrate environmental perception, intelligent recognition interaction, and communication functions. For example, an Australian studio specializing in multimedia design designed an interactive luminous wall to soothe children's emotions in the hospital and satisfy their playful nature, using 3D stereoscopic projection and motion tracking technology to replace the previous blank and boring panels with a dynamic wall that appears playful and lively. Located at the entrance of the pediatric ward, the interactive wall blends seamlessly with the interior decoration. From a distance, it appears to be just a normal wall. However, with a gentle touch, it sheds its disguise and transforms into a huge LED screen, displaying images. The wall is interactive, and the images can move and change according to the children's "commands." Children can issue commands by touching the wall, or even without touching it; simply moving near it will trigger a response!

　　In the sports field, the performance of LED displays is equally breathtaking. When LED displays are combined with third-party products, they can shine even brighter. It is reported that Nike built a stadium in Manila to promote its LunarEpic series of running shoes. There is a 200-meter track and an LED screen wall, combining product experience and service. As long as you wear Nike running shoes equipped with sensors, your speed information will be recorded during your first lap. When you run the second lap, your image will appear on the LED screen, running at the speed of your first lap.

　　The areas where LED displays contribute to the construction of smart cities are extensive, and they will not be listed one by one here. In short, in the era of intelligence, in addition to its original display function, LED displays also need to have communication, perception, interaction, identification and monitoring functions, forming various big data. LED smart city terminals can shine in public areas such as traffic control, meteorological monitoring, personnel guidance, and public security. Faced with such a huge market, how LED companies can re-layout around intelligence and interconnection in terms of corporate brands, products, and markets, and combine with the smart ecosystem, will be the focus of LED display companies.
